I have a AE CS5 project file (Windows user) that I've been working on for a few weeks now without issue but today when I tried to start up the project it keeps stalling out at 78% open and it just stays stays that way. I've closed AE out and rebooted a few times but that didn't help. I moved all the project files into another folder hoping that it was just a corrupt file holding up the project but all the project now stalls out at 88% open.

Has this happened to anyone else here on the board and are there possible fixes I could try. Would be greatful for any feedback.
